The HP Color LaserJet Enterprise M555dn error 59.f0 reports a failure in the Intermediate Transfer Belt (ITB) motor. This belt is essential for depositing toner onto the paper path; if the motor detects rotational resistance, it triggers this error code to protect the unit.
Common causes
- 1Mechanical blockage in ITB unit.
- 2Toner contamination of belt sensors.
- 3Faulty transfer belt drive motor.
- 4Loose power interface connector.
